There’s strongman training… and then there’s whatever Mark Rosenberg is doing.
The internet has been left stunned after footage emerged showing Rosenberg, known online as deadliestlift, pulling off one of the most bizarre feats of strength you’re ever likely to see — deadlifting 270lbs using only his teeth.
Yes, seriously.
The clip shows Rosenberg attached to a standard deadlift bar through a strap clenched between his teeth before lifting the entire weight clean off the floor. No tricks. No machines. Just jaw strength, neck power, and a level of commitment that most gym-goers probably can’t even comprehend.
And naturally, people online completely lost it.
At first glance, the setup looks almost impossible. The weight itself is heavy enough to challenge experienced lifters using proper lifting belts, straps, and full-body mechanics. But Rosenberg somehow manages to pull the bar from the ground while biting down on the strap, putting enormous strain through his jaw, neck, and upper body.
It’s the kind of clip that makes people instinctively wince before immediately replaying it.
While unconventional strength feats have always existed within strongman culture, lifting with the teeth remains one of the most brutal-looking displays imaginable. Unlike a traditional deadlift where the load is spread across the body, this variation appears to funnel huge amounts of pressure through an area most people wouldn’t even want to test with a shopping bag.
And that’s exactly why the reaction online has been so dramatic.
Some viewers were convinced the stunt had to be fake after seeing the amount of weight involved, while others admitted they could barely watch the clip without their own teeth hurting in sympathy. Plenty of gym fans also pointed out the sheer neck strength required just to stabilise the movement, never mind actually completing the lift itself.
One person wrote: “How the actual f*ck do you train for this?”
A second added: “If bro became a zombie it will be over for us all.”
While a third said: “Haters will say this is dangerous.”
One thing almost everyone agreed on, though, was that it looked absolutely insane.
The clip has also reignited fascination with old-school circus-style strength acts that modern strongmen occasionally revive. Teeth lifting has been around for decades in various forms, but seeing somebody perform it with a standard deadlift setup — and with that amount of weight — feels especially surreal in an era dominated by conventional gym content.
Social media is already flooded with reactions ranging from admiration to complete disbelief.
And honestly, it’s hard not to understand why.
Deadlifts alone are one of the most demanding compound lifts in strength training. Most people spend years building up to heavy numbers while using every advantage possible to protect their bodies. Rosenberg, meanwhile, appears to have looked at the exercise and decided gripping the weight with his teeth would somehow be a reasonable next step.
Whether people see it as impressive, ridiculous, terrifying, or all three at once, the video has definitely achieved one thing: everybody is talking about it.
And after watching someone deadlift 270lbs using their mouth, it’s probably going to be difficult for ordinary gym clips to feel impressive again.
